Terms for subject Environment (5171 entries)
persistence (The capacity of a substance to remain chemically stable. This is an important factor in estimating the environmental effects of substances discharged into the environment. Certain toxic substances (e.g., cyanides) have a low persistence, whereas other less immediately toxic substances (e.g., many organochlorines) have a high persistence and may therefore produce more serious effects) persistens
persistence of pesticides (The ability of a chemical to retain its molecular integrity and hence its physical, chemical, and functional characteristics in the environment through which such a chemical may be transported and distributed for a considerable period of time) bekjempingsmiddelpersistens
persistent organic pollutant persistent organisk forurensende stoff
personal responsibility personlig ansvar
pest (Any organism that damages crops, injures or irritates livestock or man, or reduces the fertility of land) skadegjører
pest control (Keeping down the number of pests by killing them or preventing them from attacking) bekjemping
pest infestation (1. The occurrence of one or more pest species in an area or location where their numbers and impact are currently or potentially at intolerable levels. 2. A sudden increase in destructiveness or population numbers of a pest species in a given area) skadegjørerangrep
pesticide (A general term for chemical agents that are used in order to kill unwanted plants, animals pests or disease-causing fungi, and embracing insecticides, herbicides, fungicides, nematicides, etc. Some pesticides have had widespread disruptive effects among non-target species) pesticid
pesticide control standard (A norm or measure applicable in legal cases pertaining to the production, dissemination or use of substances designed to mitigate or eliminate insects or small animals that harm vegetation) standard for bekjempingsmiddelkontroll
pesticide pathway (The specific or known route or vector of any chemical substance released into the environment to prevent, destroy or mitigate any pest that is directly or indirectly detrimental to harvest crops and other human interests) vei for pesticidvandring
pet (An animal which is kept in the home as a companion and treated affectionately) kjæledyr
petition right (A legal guarantee or just claim enabling a citizen or employee to compose and submit a formal written request to an authority asking for some benefit or favor or for intervention and redress of some wrong) petisjonsrett
petrochemical (Chemicals manufactured from the products of oil refineries, based largely on ethylene, propylene and butylene produced in the cracking of petrol fractions) petrokjemikalie
petrochemical industry (The production of materials derived from petroleum or natural gas) petrokjemisk industri
petrol (A fuel for internal combustion engines consisting essentially of volatile flammable liquid hydrocarbons; derived from crude petroleum by processes such as distillation reforming, polymerization, catalytic cracking, and alkilation) bensin
petroleum (A comparatively volatile liquid bitumen composed principally of hydrocarbon, with traces of sulphur, nitrogen or oxygen compounds; can be removed from the earth in a liquid state) petroleum
petroleum consumption (Petroleum belongs to non-renewable energy sources; it is a complex substance derived from the carbonized remains of trees, ferns, mosses, and other types of vegetable matter. The principal chemical constituents of oil are carbon, hydrogen, and sulphur. The various fuels made from crude oil are jet fuel, gasoline, kerosine, diesel fuel, and heavy fuel oils. Major oil consumption is in the following areas: transportation, residential-commercial, industrial and for generating electric power) oljeforbruk
petroleum geology (The branch of economic geology that relates to the origin, migration and accumulation of oil and gas, and to the discovery of commercial deposits. Its practice involves the application of geochemistry, geophysics, paleontology, structural geology and stratigraphy to the problems of finding hydrocarbons) petroleumsgeologi
petroleum industry (Manufacturing industry utilizing complex combination of interdependent operations engaged in the storage and transportation, separation of crude molecular constituents, molecular cracking, molecular rebuilding, and solvent finishing to produce petrochemical products) petroleumsindustri
